> Most neurons have multiple jobs, not a single psychological purpose. For example, neurons in a brain region called the anterior cingulate cortex are regularly involved in memory, emotion, decision-making, pain, moral judgments, imagination, attention, and empathy. One possible answer here is that these things (e.g., memory, emotion, decision-making, and pain) actually have more in common than we perceive. It's possible that mental states that seem very different to us (from "inside" our brains) are in fact quite similar (from "outside" the brain), or vice versa. The lesson may really just be that our own introspection is an unreliable guide to the actual structure of the mind.
